Answer:

Step-by-step explanation:
is essentially
(you are squaring
, so multiplying it by itself), so to simplify, you would need to distribute.
A good way to go about this is using the F.O.I.L. method, multiplying the First numbers in the parentheses, then the Outers, then Inners, and finally, Lasts.

After doing so, you would end up with
, and after combining like terms,
.
To write the expression in standard form, though, just order the terms from highest to lowest power!
Answer:
Step-by-step explanation:
a = 5b-10
a+b = 26
(5b-10)+b = 26
b = 6
a= 5b + 10 = 40
Answer:
20×(5×(-16) = (20×5)×(-16)
Step-by-step explanation:
They both equal -1600
Answer:
16
Step-by-step explanation:
(2(t3+0.5))=16(2t3+t1)
The r-value, or common ratio, can be calculated by dividing any two consecutive terms in a geometric sequence.
